No reason not to believe it; BMW indeed understates their performance. Owning a 318D 143HP Luxury (= same 320D motor, main difference is programmed to deliver lower power), I can confirm the car drives really comfortable, well balanced to drive either sporty / comfy. Equipped with a state of the art 8AT gearbox, exclusive package (HighBeam auto adaptive xenons) and HUD contributing safety driving features.
